How can the head be treated with kerosene for lice and nits? - briefly
Apply a small amount of food‑grade kerosene to the scalp, massage gently, cover the head with a plastic cap for 30–45 minutes, then comb out lice and nits and wash the hair thoroughly with mild soap. Use caution: keep away from flames and ensure the scalp is rinsed completely to remove any residue.
How can the head be treated with kerosene for lice and nits? - in detail
Kerosene can be employed as a contact insecticide to eradicate head‑lice infestations, but its use demands strict adherence to safety protocols. The substance functions by coating the hair shafts and suffocating both adult insects and their eggs.
First, select a low‑smoke, food‑grade kerosene and verify that the container is clean and free of contaminants. Prepare a work area with good ventilation, lay down disposable sheets, and keep children and pets away.
Apply the liquid to dry hair using a clean dropper or a small bowl, ensuring complete saturation from scalp to tips. A typical volume is 1–2 ml per 10 cm of hair length; excess fluid should be avoided to reduce the risk of skin irritation. After application, cover the head with a tight‑fitting, non‑absorbent cap or plastic wrap for 10–15 minutes. The cap prevents evaporation and maintains the insecticidal layer.
During the exposure period, monitor the scalp for signs of burning, redness, or excessive itching. If any adverse reaction occurs, remove the cap immediately, rinse the hair thoroughly with lukewarm water, and wash with a mild soap.
After the allotted time, rinse the hair repeatedly until all kerosene residues are cleared. Follow with a regular shampoo and a conditioner to restore moisture. Comb the hair with a fine‑toothed nit comb, removing dead insects and eggs. Repeat the combing process daily for a week to capture any newly hatched lice.
Safety considerations include:
- Conduct a patch test on a small skin area 24 hours before full application.
- Avoid use on broken skin, scalp dermatitis, or in individuals with known petroleum sensitivities.
- Do not apply near eyes, nose, or mouth; protect these areas with a cotton barrier if necessary.
- Store kerosene out of reach of children; keep the container tightly sealed when not in use.
Because kerosene is flammable, keep all ignition sources away during and after treatment. Dispose of used caps and wipes in a sealed bag to prevent accidental fire hazards.
Medical guidance recommends limiting kerosene treatments to a maximum of two cycles, spaced one week apart, and seeking professional advice if the infestation persists. Modern pediculicides—such as permethrin or ivermectin shampoos—offer lower toxicity and are generally preferred, but kerosene remains an option in settings where conventional products are unavailable, provided the outlined precautions are rigorously followed.
